HF Series Shunts




HF500 Shunt

HF500 Shunt




The HF series shunts provide an accurate current sensing solution for many wideband power measurement applications up to 500Arms. While the HF series was primarily designed for use with the PPA series power analyzers from N4L that provide exceptional wideband accuracy, dynamic range and common mode rejection, the HF series can be used as a precise current sensing device for other equipment.
